The machine will ring (2 - 3 times), but no fax comes through. I unplugged it from the power and phone line for about 30 - 60 seconds, still nothing, not sure what the problem is.

Step by step information at the link below.
Brother Fax T96
The F/T Mode is used to allow the fax machine and the telephones to share the same telephone line. When a call comes in, the fax machine and all extension telephones on that line will ring according to the number of rings you have set for the Ring Delay.
When the Ring Delay is completed, the fax machine will answer the call and determine if it is a fax call or a telephone (voice) call.
The fax machine can determine this by the signal it is receiving on the telephone line. If someone is sending a fax automatically , the sending fax machine will transmit a fax tone (a series of beeps every 3 seconds).
If your fax machine hears these tones, it will receive the fax.

If the fax machine does not hear any fax tones, it assumes it is a telephone (voice) call and will begin ringing the F/T ring tones (double ring) for the length of time you selected for the F/T Ring Time. These tones will only ring on the fax machine's handset (extension or external phones will not ring). At the end of the F/T ring time the fax machine will go into the receive mode in order to receive a manual fax.
(If the call was a voice call and was not answered, the caller will hear the fax receive tones also).

• If you answer the call before the fax machine(during the ring delay period) and determine it is a fax, you can transfer the fax to the fax machine for receiving.
  
  
• If you answer the call on an "extension" phone and hear a beep every 3 seconds (automatic fax) or silence (manual fax), press *51 or *91 for New Zealand (remote activation code) on the telephone keypad, wait to hear the fax machine turn on (chirping sounds) and then hang up.
  
  
• If you answer on the handset of the fax machine and hear a beep every 3 seconds or silence, press the Fax Start or Start/Copy key on the control panel of the fax machine and then hang up the handset.
  
  
• If you answer a call on an "extension" phone during the F/T Ring Time, you will hear the F/T ring tones.
  To release the call from the fax machine, press #51 or #91 for New Zealand (remote deactivation code) on the telephone keypad and you can speak to the calling party.
  
  
• If you pick up the handset of the fax machine during the F/T ring time, you may talk to the calling party immediately.

have you see the display if it was saying the word receiving...?

let me know..

Unplug the phone line from the fax machine. Wait at least 1 minute then call the phone number that goes to the fax machine from another line such as a cell phone. Make sure you get a ring and not a busy signal. If you get a ring then hang up the phone. Plug in the fax machine again and call the fax number again. If you get a busy signal then either your phone if off the hook, the switch that is actuated when the phone is placed in the cradle is bad or your modem in the fax machine itself has gone bad. Another thing to try is unplug the fax machines power cord for 30 seconds then plug it back in. I have seen the modems get "locked up" and keep the phone line open. Unplugging will sometimes reset this and get it working again.
Good Luck and Thank You for using Fixya.

The mode is correct. You can check the rings to answer setting. Default is 4 rings. If your phone line is just for the fax try setting rings to 1. Sometimes sending fax machines go into redial before the 4th ring.

Also, sometimes unplugging the power for 10 seconds will clear any memory that may have locked up the machine.

Hope this helps.

Check the phone line with a basic old phone plug it into the fax line do you get a good dial tone, and no noise on line. Also check the phone line call ATT and have them check the number move the fax machine to different plug. power off the wait tens second power on. check the phone line connector.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

You need to purchase a cross-over cable to use on your fax machine. This cable will change line 2 to line 1 for the fax so it will pick up the line when line 2 rings and not line 1.

If you want to use a regular cable you'll have to have someone rewire the jack in the wall to swap line 1 and line 2, then just plug the fax machine into this jack.

Make sure that if you DO NOT subscribe to DISTINCTIVE RING that it is set to the OFF SETTING! had to figure this out on my own!

Press the OUT button.

Unplug the power cord for 10 seconds.

If all else fails:

Open the toner door

Press FUNCTION
press 7
Press monitor key slowly 4 times
press *
press 6
scroll down to ALL JOB CLEAR
press SET.

or

scroll down to SHIPMENT SET
press SET
press 2

machine will reboot

Do you a DSL or any other kind of digital phone line?

Unplug the power cord for 10 seconds.

try unplug the phone line and use another phone to call again, then c if it has a fax tone, if it does, there might be another fax machine that picks up the fax before the Dp-190 pick up the fax.

another thing you can try is to change a new phone line that connect between ur machine and the plug.
